Since the Light is literally what caused all life and sustains it, what the tauren is advocating is similar to something CS Lewis said “they cut off the branch they are sitting on.”
Life is what you make of it. Some people take life and make it something wonderful. Others make it something horrific. Of itself it’s neither good nor evil. It makes good and evil possible.
My understanding is that each primal force is trying to take over the universe and are only kept in check by the other primal forces. The Light is no different from Fel, Void, Life, Arcane or Death (and any other force I forgot). They’re all trying to take over and the sad reality is that we’re helping imbalance them by killing them.
Fel was keeping Void in check and now that we’ve dealth with Fel, Void is going crazy but Void is keeping Light in check so when we kill the Void leaders the Light is going to surge. The cycle will continue because we’re disrupting the balance.
She did respond though. I’m pretty sure that everything Tyrande does is because Elune allows her to. Plus she gave us these wonderful eyes that let us sneak up on you even better.
What makes life good? What is good for one life form can be devastating for another. Nature does one thing very well…kill. Life is very closely entwined with death.
A plague running rampant is a blossoming of life, but for those afflicted with that life, it means death.
Extinction is the way of life.
Decimating the human population would allow other life to flourish here on our planet.
She did what she was able, she gave them painless death.
